GUWAHATI, 23 FEB: Under India’s presidency of the G20, the Indian Institute of Technology (IIT) Guwahati has made a significant contribution to building a sustainable future through the construction of a 3D printed security post.
The post, constructed using M40 grade sustainable concrete, contains industrial waste, fibers, and chemical admixtures. Developed by a team of innovators at IIT Guwahati’s startup Stratify 3D Pvt. Ltd., this automated technology is in line with India’s #AatmaNirbhar Bharat vision, promoting self-reliance and innovation.
The 3D printed security post has a carpet area of 85 sq. ft. and consists of 56 modules. Custom-designed tetrahedron modules with overhang features of 22 degrees and embossed features up to 40 mm were printed using an automated concrete 3D printer in 15 hours. The modules were assembled on-site using a special bonding agent. The security post is sustainable in terms of construction practice and material composition and is expected to provide customized houses in India with controlled quality in less construction time.
Dr. Biranchi Panda, Assistant Professor in the Mechanical Department at IIT Guwahati, said, “In this project, we addressed aesthetic potential of digital construction technology while utilizing sustainable construction materials. Material and surface texture demonstrate the remarkable aesthetic possibilities of concrete printing technology used for the security post-construction.”
The construction sector represents 13% of the GDP and produces approximately 40% of total carbon dioxide (CO2) emissions. Emerging technologies such as 3D printing can play a vital role in achieving a circular construction economy by integrating new sustainable materials derived from industrial waste with multi-functionality properties.
Speaking about Industry 4.0 as a priority of G20 under India’s presidency, Prof. Parameswar K. Iyer, Officiating Director, IIT Guwahati, said, “Advancements in technologies such as ‘additive manufacturing’, also known as 3D printing, using sustainable and locally available resources enable new location-specific designs and modern economical structures.”
The 3D printed Security post’s on-site assembly and technology demonstration were showcased during the Y20 Inception Meet at IIT Guwahati. The post was then formally handed over to the security personnel to start its operation in the presence of Prof. Parameswar K. Iyer, Officiating Director, IIT Guwahati; Superintendent Engineer Col. L.K. Singh (Retd.); Associate Dean IPM K.D. Singh; Dr. Biranchi Panda, Assistant Professor, IIT Guwahati, and Stratify 3D Team.
With this innovative 3D printing technology and sustainable construction materials, IIT Guwahati has taken a significant step towards building a more sustainable future.
